Shape -
Slender, soft, curved and spiral
-
one Form and structure: The spirochete is thin and consists of spiral columnar protoplasts, internal flagella and outer membrane. The diameter is generally 0.1~0.3 μ m, with different lengths and helicoids, but the leptospira is C or S shaped. Spirochaeta Gram staining is negative, but not easy to stain, so Fontana silver plating staining method is commonly used. -
two Culture characteristics: Various spirochetes have different physiological needs, and their energy comes from sugars, amino acids and long-chain fatty acids. -
three Antigenic composition: The antigenic components of most spirochetes mainly include outer membrane protein and inner flagellar antigen, while other antigenic components vary from bacterium to bacterium. -
four Resistance: The resistance of spirochetes is weak, but Leptospira Is more resistant than Treponema pallidum 。
-
one Pathogen examination: The movement of spirochetes can be observed with a dark field microscope; Polymerase chain reaction (PCR) can also be used to detect the DNA of spirochetes. -
two Serological test: Leptospira can be tested by microscopic agglutination test, complement binding test and indirect agglutination test; Treponema pallidum can use fluorescent treponema antibody binding test and Treponema pallidum immobilization test.
